To all whom it may concern. 7

Be it-known that I, AXEL JULIUS LAURITS LASSEN, a citizen of theiKing dom ofljenmark, residing at No. 5Aaboulevard, Copenhagen,;Denmark, have invented certain new. and useful Improvements.in- -Machines for Closing Bottles and the like with Capsules, of which the following is a specification.

This invention refers to a machine for capsuling bottles and,like receptacles (both such as contain-liquids under-pressure,.for instance beer, andsuch as contain liquids not subjectedto pressure, for instance milk), the capsuling being accomplished bywrneans of capsules of. some suitable metal eventually lined with some soft packing, or tightening-material, for instance paper, cork, or the like.

Capsuling machines heretofore in use were disadvantageous forthe most part because of the ineffectual manner in which the mandrel over which the icapsule is shaped is operated. This operation must take place quickly and reliably, and the ll d m stand steady and firm iwhile, the; capsule .is being shaped over it. i i

A characteristic feature of the present invention is that thernandrel is swung from below up against the capsule-blank which is disposed under the sleeve-shaped pistonhead, the capsule-blank having beenpreviously stamped out bythe piston. i

The mandrel first presses. the blank a short distance upl zinto the-piston-head, so

that'the blank is given the shape: ojf a fiattened capsule, and is then swung'to one side, after which the bottle (while the capsuleblank is held fast in the aforesaidposition) is carried qupward, pressing the capsuleblankstill higher up into. the hollow pistonhead, whereby the capsule-blank is given its final shape and is caused completelyto, embrace the -ridge or fiange on the neck-of 1 w f In the machine which serves. to perform this operation, the imandrel; overywhich the capsuleis shapedeis-made fast to a movable member" which can turn aroundfan agilebolt, on thelike, fixed in the-machineframe, and which gets its motive power 'fromj the main shaft of the machine.

-One form for construction, of this machine is shown in the-drawing, in which, Figure l is .a, side-view-of the machine, partly-in section, r H l 2 is a front view of the same;

Application filed July 16, 1915. Serial No. 40,209.

Fig. 3 is the mandrel over which the capsule is first shaped,but in another working position than in Fig. 1

Figafl showsthose parts of the machine by means of which the capsule is given its temporary shape (larger scale) and ,,Fig. ,5 shows the parts. which serve to press the capsule on to the bottle (also larger scale) In the frame 1 of the machine there are bearingsrforthe main shaft 2, which is run by means of apulley 3, and which carries cams, 4:, 5 and 6, by means of which the different members ofthe machine are moved. The came, as shown in Fig. 2, has a groove 7 in whichn pin 9, furnished with aroller 8 moves. l

qThe pin 95isdisposed on a crosshead 10 which is guided in a sleeve 11 secured to the machine-frame, the sleeve being adjustable by means of the flanges 12. Thecrosshead 10 is hollow, and in its hollow part can slide a sleeve 13 which embraces a spiral spring 14 and, an ejecting-piston 15.

i ,In thetop ofnthe sleeve 13 is screwed a pin 16 projecting through a hole in the crosshead 10 and being actuated, during the other bolt. 20, which is passed through a similar hole 21 in the sleeve. On the lower part of the crosshead 10, the piston proper 22 is securedby means of a hollow cylinder 23 screwed into the crosshead and furnished with a-nut 2 1.

- The piston 22 is hollow and embraces an ejector- 25, which bymeans of a collar 26 restson the upper edge of the piston, so thatit cannot fallout. The ejecting piston 15 rests, {in itsnormal position, against the upper side of the ejector 25, as shown in Under the piston 22 there is disposed a cutting-ring 28'inserted in a plate5et whose edge,,53 projects a little in front of the edge of thelhole in the cutting-ring 28. The plate 54 is carried by a bracket 27 projecting from the machine framev 1, and under the bracket-27 there is a device for guiding the bottles-29, .which rest on a table 30, whose .carrier-pin31 can move in a guide 32.- The stretched by the mandrel 38 to the form or:

table 30 is raised and lowered by means of a lever 33, capable of turing around a bolt 56 in the bracket 55 carrying the'guide 32, and being actuated by a rod 34 which at its top has a roller 35, which is pressed up against the cam 6.

A sector 37, which turns on a bolt 36, which has its bearing in the machine-frame 1, carries a mandrel 38, over which the capsule-blank is given a temporary shape. The mandrel 38 itself is secured to the sector, and, as specially shown by Fig. 3, is surrounded by a ring, namely the removalring 39, which, by means of pins 41, rests on the plate 40. The lower surface of this plate is actuated by a pawl 42 rockably disposed in a hollow in the sector 37, said pawl being actuated by a spiral spring 43, in such a manner that it always tends to hold the removal-ring 39 up on a level with the upper surface of the mandrel 38, as shown in Fig. 3.

To the sector 37 is secured an arm 44, and between this arm and the sector there is disposed a roller 45, which is placed on the end of the lever 46. This lever is movable around a pin 47 stationarily disposed in the machine-frame, and is actuated by means of a link 48 from the rod 49, which at its top carries a roller 50 actuated by the cam 5.

Furthermore. the machine is furnished with a device for the automatic feeding of the capsule-blanks. This device, which is not shown on the drawing, is of a kind already known, and will therefore not be described here.

The main shaft 2 is provided with a clutch 51 which, bv means of a traction-rod 52 is closed when the machine is started, which may be accomplished either by hand or foot pressure. 7

The machine works in the following ner:

During the rotation of the main shaftta 2, the piston 22 is carried down toward the sheet of metal which is fed in between the piston and the cutting-ring 28 and cuts out the capsule-blank. At the same time that the piston 22 goes down to this position,- where it temporarily remains, the sector 37 is turned upward, so that the mandrel 38' is carried up into the hollow part of the piston 22 into the position shown in Fig. 4. The removal-ring 39 is pressed downward by the edge of the piston 22, firmly the cap blank 52, so that the same is shape of a shallow cup with its bottom 1, turned upward and with a ring-shaped l downward-bent rim. The sector 37 then re-@ cedes, and the removal-ring 39 at the same "Y times pushes the blank 52 out over the mandrel 38, so that the blank remains in the? lower part of the hollow part of the piston 22, where it is frictionally held fast by rim below said piston,

means of. its own elasticity. For further of the bottle, and the rim of the capsuleblank 52 is straightened out and caused to hug the neck of the bottle. Finally, when the table 30 is lowered, at the same time that the piston moves upward, the capsuled bottle is removed from the piston 22 by means of the ejector 25 loosening the capsule from the piston, owing to the fact that the sleeve 13, which at this moment is given a pressure by the lug 17 by means of the pin 16, aetuates the ejector 25 (on its head 26). Then the capsuling is finished.

Grooves or rifles may be cut on the inner surface of the lower edge of the piston 22 which. will stamp the edge of the capsule in such a way that, when it is put in place on the neck of the bottle, its edge will be fluted where it is pressed around the ridge or flange on the neck of the bottle. This capsule has an outer resemblance to the wellknown crown cork.

The sealing disk lies on the top of the neck of the bottle, but since the tighteningmaterial, together with the capsule, is also pressed down over the sides of the neck of the bottle, a still tighter and more efficient closing is accomplished.

I claiml. A machine for placing capsules on bottles, comprising means for supporting a capsule-blank, a sleeve shaped piston above said blank holder, a mandrel swingingly mounted below said holding means, and adapted to be swung upward against the capsule blank, and to coiiperate with said piston to shape said capsule into a relatively shallow capsule pressed into said piston and having a laterally extending rim below said piston, a bottle support adapted to bring a abottle into contact with said capsule upon tlremoval of said mandrel, and to press said il'capsule and lateral rim into said piston to ipjform the same into a relatively deep cappltsule embracing the head of the bottle.
